Selective journalism it seems. It seems to imply that this person is the guru on the issue and in inference pretends that it is Julia Gillard and Bob brown who came up with the global warming concept. No mention of the fact that the deniers in the science arena are in fact a minority. Just a partisan political statement that actually adds little to the debate. We can all come up with experts who have a contrarian view. On climate change the main view is that climate change is a real phenomona because of global warming.
